Plasma cutting equipment uses high open circuit voltages to initiate the plasma arc. Normal load
voltages are higher than experienced with other types of welding equipment. Extreme CAUTION
must be exercised when operating or servicing this equipment.

9
PERSONAL PROTECTION-
•Keep the operator’s body and clothing dry.
•Do not stand, sit, or lie in/on any wet surfaces when using this equipment.
•Never work in a damp or wet area without proper insulation against electric shock.
•Disconnect main power before servicing the torch, power supply or service connections to
the plasma arc system, or any part of the machine bed.
•Wear adequate personal equipment (overalls, gloves, safety boots etc.) when operating the
machine.
•Remove or secure articles of clothing, such as ties and loose sleeves, which may catch or be
drawn into moving machinery.

10
Eye Protection-
Medical treatment facilities and a qualified first aid person should be available for immediate
treatment of flash burns to the eyes and skin.
It is recommended that the cutting area be prepared in such a way as to minimize the
reflection and transmission of ultra-violet radiation. Walls and other surface areas should be
painted in dark colors to reduce reflection. Protective screens or curtains may be installed to
avoid unnecessary ultra-violet transmission.

11
INPUT CONNECTIONS-
1. A wall mounted line isolating switch, fused as required by local electrical codes, must be
fitted as close as possible to the plasma arc power supply.
2. Three-phase input conductors must be sized to carry the rated current of the plasma arc
power supply.
3. Primary power cable must be provided with a minimum 600v rating.
GROUNDING-
Input Power-
1.) Connect the ground lead of the four-conductor / three phase input cable to the electrical
system ground in the disconnect box and the ground stud provided in the plasma arc supply.
2.) Be sure all ground lugs are of adequate size to carry the rated current load.
3.) Make all connections tight to avoid resistance heating.

12
GROUNDING (Cont’d.)
Output Power-
1.) Connect all positive output ground leads to the material grid of the worktable.
2.) Connect the material grid of the worktable to a good earth ground.
BURN PREVENTION-
High intensity ultraviolet and infrared radiation is produced by the plasma arc and is of
similar intensity to typical high current welding arcs. This radiation is damaging to the eyes and
skin. As the operator comes closer to the torch, the level of exposure increases rapidly.

13
TOXIC FUMES-
Proper precautions must be exercised to prevent the exposure of others in the vicinity to toxic
fumes that may be generated while plasma cutting.
Certain chlorinated solvents such a perchloroethylene and trichlorethylene will decompose under
ultraviolet radiation to form phosgene and other gasses. Care must be taken to avoid the use of
these solvents on materials being cut with plasma arc cutting equipment. Containers of these
solvents and other degreasing agents should be removed from the immediate area around the
plasma arc.
Metals coated with or containing significant amounts of lead, cadmium, zinc, mercury, or
beryllium can produce harmful concentrations of toxic fumes when the plasma arc cuts. Adequate
local exhaust ventilation must be used, or the operator must be supplied with special equipment
to guarantee a supply of fresh air such as a respirator or air supplied helmet.
Metals coated with materials that emit toxic fumes must not be cut unless:
1.) The coating is removed prior to cutting.
2.) The area is adequately ventilated.
3.) The operator is supplied with fresh air breathing equipment.

14
AIR CONTAMINATION-
The plasma cutting process generates large quantities of hot metal dust and fumes that would be
hazardous if uncontrolled. A blower pulls a vacuum through the fume extraction assembly in the
bed of the machine. The blower pulls the dust-laden air through a customer supplied filter before
exhausting the air to the environment.
The gases listed below either are produced normally during plasma arc cutting or can form under
certain conditions.
Ozone-
Ozone is produced by the reaction of the plasma arc's ultraviolet radiation with oxygen in the air.
Uncontrolled, excessive levels of ozone can constitute a hazard. When there is proper venting to
the outside and the machine's internal ventilation system is functioning properly, there is
adequate control of ozone during torch cutting.
Nitrogen Dioxide-
Nitrogen dioxide gas is produced when nitrogen and oxygen in the air pass through the electric
arc. A hazard may exist if uncontrolled, excessive levels of nitrogen dioxide are formed. With
proper venting to the outside, the machine's internal ventilation system is adequate to control
nitrogen dioxide during torch cutting, if the system is functioning normally.

15
AIR CONTAMINATION (Cont’d.)-
Acetyl Chloride-
Acetyl chloride gases form in the air surrounding the plasma arc when the airborne vapors of
chlorinated solvents or degreasers decompose upon being exposed to the ultraviolet radiation of
the arc. A hazard may exist if uncontrolled, excessive levels of acetyl chlorides are formed.
A pungent "sweetish" aroma like chlorine bleach is the first sign that these gases are being
produced. Shut down the plasma arc cutting system immediately if you detect the acetyl chloride
odor. Do not resume cutting until you locate and control the source of the vapors. Various
cleaning solvents and vapor degreasers contain chemicals that decompose rapidly when exposed
to ultraviolet radiation.
If the solvents, cleaning solutions, or vapor degreasers used in the shop contain any of the
following chemicals, Do Not use them near the “Plasma Arc Cutting System:
1.) Trichloroethylene
2.) Trichloroethane
3.) Perchloroethylene
4.) Per-chloroethane
5.) Trifluoro-Trichloroethane (Fluorocarbon-113)

16
AIR CONTAMINATION (Cont’d.)-
These chemicals also decompose into small amounts of the toxic gas’s phosgene and chlorine. You
will notice the acetyl chloride odor long before phosgene or chlorine levels become harmful. The
vapors can decompose up to several feet away from the arc, do not rely on the machine's internal
ventilation system to control solvent vapors and their products.
Do not use or store chlorinated solvents, cleaning solutions, and vapor degreasers close to the
machine, where the vapors can enter the torch-cutting area.
NOTE: It may prove advisable to provide separate ventilation for the solvent/degreaser storage
area.
Metal Fumes-
Metal Fumes are produced when the plasma arc vaporizes the metal. A hazard may exist when
uncontrolled, excessive levels of metal fumes are produced some vaporized metals form toxic
gases. These metals may be in their pure metallic state, in an alloy, or in a coating such as paint or
plating. Metals that are known to produce toxic fumes include beryllium, cadmium, lead,
manganese, mercury, and zinc. Beryllium products require particular care because their fumes are
highly toxic. If there is proper venting to the outside and the machine's internal ventilation system
is functioning normally, there should be adequate control of metal fumes during torch cutting.

17
AIR CONTAMINATION (Cont’d.)-
Metal Dust-
Metal Dust is formed as metal vaporizes during torch cutting. A hazard may exist when
uncontrolled, excessive levels of metal dust are produced. If there is proper venting to the outside
and the machine's internal ventilation system is functioning normally, there should be adequate
control of metal dust during torch cutting. For proper ventilation, at least 90% of the worktable
should be covered by the workpiece (or other sheet metal covers).
See dust collector vendor installation and operation manual for additional precautions.
FIRE PREVENTION-
All combustible materials must be removed from the immediate cutting area to at least 35 feet
away. Appropriate fire extinguishing equipment must be available in the immediate cutting area.
After cutting, be sure to allow the metal to cool sufficiently before handling or before allowing
contact with combustible materials.

18
FIRE PREVENTION-
Never plasma cut empty containers that have held toxic or potentially explosive materials. Those
containers must be thoroughly cleaned according to national standards prior to cutting or
welding. Never plasma cut in an atmosphere that contains heavy concentrations of dust,
flammable gas, or combustible liquids (such as petrol).
Cylinders-
Compressed gas cylinders must be handled and used in accordance with appropriate national
safety standards.
•Never use a cylinder that is physically damaged or leaks.
•Never move or transport a cylinder without the protective valve cover in place.
•Never use a gas cylinder or its contents for any other purpose than that for which it
is intended. •Never lubricate cylinder valves with oil or grease.
•Never allow electrical contact such as welding arcs with cylinders.
•Never expose cylinders to excessive heat, sparks, slag, or open flames, which may
cause rupture.
•Never use hammers, wrenches, or other tools to open stuck valves. Send these
cylinders back to the supplier.

19
Pressure Regulators-
All regulators used to operate plasma equipment must be maintained in proper working
condition. Faulty equipment can cause equipment damage or operator injury. Faulty equipment
must be serviced at the manufacturers designated facility by trained repair technicians.
•Never use a regulator for any other gas than that for which it is intended.
•Never use a regulator that leaks, excessively creeps, or is physically damaged in any way.
•Never attempt to lubricate a regulator with oil or grease.
HOSES-
Gas hoses used for Plasma Arc Cutting Systems adhere to the following Color Coding:
Red ............. Acetylene.
Orange ........ LPG.
Blue............. Oxygen.
Black ........... Inert Gases and Air.

20
Pressure Regulators (Cont’d.)-
Replace any hose that is damaged by physical abuse or from sparks, heat, or open flame. Lay
hoses out straight to prevent kinks. Coil excess hose and place out of the way to prevent loose
connections, or other damage. Keep hose lengths to a minimum to prevent damage, reduce
pressure drop and prevent possible volume flow restriction. Please refer to national standards for
more information on hoses.
SAFETY DEVICES-
Plasma Arc Units are provided with certain safety interlocks designed to prevent equipment
damage and/or personal injury. Never short out or in any way attempt to defeat the safety
interlock devices.
All exposed electrical connections must be covered with the proper insulation material. Safety
devices must be regularly checked for proper operation and replaced immediately if found to be
inoperative.
